older pics on my SD card (up to 11/2016) are viewable on my camera and can be viewed and copied to my computers... but my more recent pics (from 12/2016) are viewable only on my camera. I've tried my laptop and my desktop and neither one can show the more recent pics...
 
Have you tried leaving the SD card in the camera and then connecting the camera (via USB cord) to the computer and transferring them that way?
